Abraxas- hmm, it is out there but, I LIKE it. I'm sure if it's useable, however.Luciano- I could see both sides of this. People are starting to gravitate toward softer boys names, so Luciano could fit right in. On the other hand, he may be too unheard of.Macario (ma KAR ee oh)- Easy to pronounce and spell. Yes, I think this is useable, although it would work best if you are of Hispanic descent.Marco- Useable. I know a Marcos, so why not Marco?Calder- I think that with the more frequent surnames-used-as-first-names and ending-in-er names Calder would work well.Abram- Yes, useable in my opinion. Amadeus- I love this and think it would be adorable on a little boy. It would work best if you are a fan of the composer, I think.Nazario- I don't think the world is ready for this one yet.Arlo- Useable, older boys names are roaring back into use!Gage- I like it. Shorter boys names and names in general are on the rise. I think it would fit right in with all the Jacks and Mays.Bronx- Mmm....I don't know. I think you would always get a lot of comments on this name.Dashiell- I've seen this popping up more and more on the message boards and, though I'm not a fan, I believe it to be useable.
